@Ph3noM Yes, images are temporarily stored in /images/dev/<MAC-ADDRESS> when being uploaded. Don’t worry about /tmp/pigz1 that’s just an internal thing (actually a pipe to compress the data before writing it to the image file).

After the upload is done the image should be moved from /images/dev/<MAC-ADDRESS> to /images/<IMAGE-NAME> (not /images/dev/<IMAGE-NAME>). Please move it to the proper location and you should see “size on server”. As well deploy should work then.

But one question remains: Why is it not moved properly? In pretty much 99% of the time this is because your FTP settings are screwed up. Follow the FTP troubleshooting guide. If you still can’t fix this I ask you to show us the output of mount and df -h commands on your FOG server.
